Highly Energy Release of Aluminum@Ammonium Perchlorate Composites Incorporated with Graphene Oxide‐based Energetic Coordination Polymer

Abstract Achieving high energy release of aluminum (Al) and ammonium perchlorate (AP) is of significant importance in the realm of energy materials. In this work, integrated Al@AP/GO‐CHZ‐M (M = Co 2+ or Ni 2+ ) composites are successfully synthesized through an integrated design and precise catalysis approach. The integrated Al@AP/Co composites exhibit fast decomposition, with a 76.6 °C reduction in decomposition temperature and a 66.0% increase in heat release compared to Al+AP mixture counterpart. From a kinetic perspective, the decomposition activation energy for Al@AP/Co is largely decreased by 215.5 kJ mol −1 (−67.4%) and its kinetics shifted to an autocatalytic model. Transition metals in GO‐CHZ‐M…
